Unix Command History – Access on the Fly

command historyshell

For example, if I do a

mkdir thisismyfolder912

I remember there is some easier way to switch to thisismyfolder912 than having to do a

cd thisismyfolder912

What is that way and how does it work? Also, what are the other ways I can use this?

Are you talking about classic history expansion, or Readline processing? cd !$ on the next input line will substitute in the last argument of the previous line, or M-. or M-_ will yank it using Readline.

bash – Preserve Bash History in Multiple Terminal Windows

Add the following to your ~/.bashrc:

# Avoid duplicates
HISTCONTROL=ignoredups:erasedups
# When the shell exits, append to the history file instead of overwriting it
shopt -s histappend

# After each command, append to the history file and reread it
PROMPT_COMMAND="${PROMPT_COMMAND:+$PROMPT_COMMAND$'\n'}history -a; history -c; history -r"

How to set an unlimited size to the history file for tcsh

Here is a good starting point:

http://hints.macworld.com/article.php?story=20070715091413640

set history = 2000          # History remembered is 2000
set savehist = (2000 merge) # Save and merge with existing saved 
set histfile = ~/.tcsh_history
 ...in .tcshrc and this line... 
history -S
 ...in .logout solved the problem.

Now history is not only preserved between Terminal sessions, but also merged (considering command dates).

Another note, just because the login shell is tcsh doesn't mean you have to use it. Do you have bash installed? Can you run:

$ bash

If that works, you can just put a 'bash --login' in your .tcshrc and then use bash (or zsh if you are feeling advantageous).
